Abstract

La présente invention concerne des systèmes et des procédés de classification de tissu utilisant des techniques ultrasonores quantitatives. Les paramètres sont calculés directement à partir de données brutes de signal d'écho acquises d'une région d'intérêt durant un balayage ultrasonore et des cartes paramétriques sont produites en utilisant ces paramètres. Ces paramètres peuvent être calculés après normalisation des données de signal d'écho en utilisant des données de référence pour mitiger les effets des variations sur les réglages des instruments, la diffraction du faisceau ultrasonore, et les effets d'atténuation. Des mesures statistiques de premier ordre et de second ordre sont calculées pour ces cartes paramétriques et sont utilisées pour classer le tissu ou les tissus dans la région d'intérêt. L'utilisation de ces systèmes et procédés permet de classifier le tissu avec différents niveaux de classification. Par exemple, un tissu caractérisé comme un cancer malin peut en outre être classé (par exemple, grade I, II ou III).
